While the differences between these 4-year-old girls may be obvious to some, they see only their similarities.

In fact, Jia Sarnicola and Zuri Copeland believe themselves to be so similar, they’re not just best friends – they’re “twins”.

While some might scoff at the childlike innocence, Jia and Zuri recently made international headlines when another youngster at a birthday party claimed that the girls couldn’t be twins because they did not have the same skin color.

Jia fiercely retorted by saying: “You don’t know what you’re talking about. We’re twins because we share the same soul.”

The girls remain steadfast in their belief that adults just don’t get it; love can overcome any boundary.
